        Workflow explanation

        Preprocessing of reads was done automatically with workflow tool seq2science v0.5.6. Public samples were downloaded from the Sequence Read Archive with help of the ncbi e-utilities and pysradb. Genome assembly GRCm38.p6 was downloaded with genomepy 0.10.0. The effective genome size was estimated per sample by khmer v2.0 by calculating the number of unique kmers with k being the average read length. Paired-end reads were trimmed with fastp v0.20.1 with default options. Reads were aligned with bwa-mem v0.7.17 with options '-M'. Afterwards, duplicate reads were marked with Picard MarkDuplicates v2.23.8. Mapped reads were removed if they did not have a minimum mapping quality of 30, were a (secondary) multimapper, were a PCR/optical duplicate, aligned inside the ENCODE blacklist or had a template length longer than 150 bp and shorter than 0 bp and finally were tn5 bias shifted by seq2science. General alignment statistics were collected by samtools stats v1.14. Peaks were called with macs2 v2.2.7 with options '--shift -100 --extsize 200 --nomodel --buffer-size 10000' in BAM mode. The effective genome size was estimated by taking the number of unique kmers in the assembly of the same length as the average read length for each sample. Deeptools v3.5.0 was used for the fingerprint, profile, correlation and dendrogram/heatmap plots, where the heatmap was made with options '--distanceBetweenBins 9000 --binSize 1000'. Narrowpeak files of biological replicates belonging to the same condition were merged with fisher's method in macs2. The fraction reads in peak score (frips) was calculated by featurecounts v1.6.4. A peak feature distribution plot and peak localization plot relative to TSS were made with chipseeker. A consensus set of summits was made with gimmemotifs.combine_peaks v0.15.1. The UCSC genome browser was used to visualize and inspect alignment. All summits were extended with 100 bp to get a consensus peakset. Finally, a count table from the consensus peakset with gimmemotifs. Differential accessibility analysis was performed using DESeq2 v1.30.1. To adjust for multiple testing the (default) Benjamini-Hochberg procedure was performed with an FDR cutoff of 0.1 (default is 0.1). Counts were log transformed using the (default) shrinkage estimator apeglm v1.12.0. Quality control metrics were aggregated by MultiQC v1.11.

        Number of reads, categorised by duplication state. Pair counts are doubled - see help text for details.

        The table in the Picard metrics file contains some columns referring read pairs and some referring to single reads.

        To make the numbers in this plot sum correctly, values referring to pairs are doubled according to the scheme below:

        • READS_IN_UNIQUE_PAIRS = 2 * (READ_PAIRS_EXAMINED - READ_PAIR_DUPLICATES)

        SamTools pre-sieve

        Samtools is a suite of programs for interacting with high-throughput sequencing data.

        The pre-sieve statistics are quality metrics measured before applying (optional) minimum mapping quality, blacklist removal, mitochondrial read removal, read length filtering, and tn5 shift.

        Percent Mapped

        Alignment metrics from samtools stats; mapped vs. unmapped reads.

        For a set of samples that have come from the same multiplexed library, similar numbers of reads for each sample are expected. Large differences in numbers might indicate issues during the library preparation process. Whilst large differences in read numbers may be controlled for in downstream processings (e.g. read count normalisation), you may wish to consider whether the read depths achieved have fallen below recommended levels depending on the applications.

        Low alignment rates could indicate contamination of samples (e.g. adapter sequences), low sequencing quality or other artefacts. These can be further investigated in the sequence level QC (e.g. from FastQC).

        deepTools - Spearman correlation heatmap of reads in bins across the genome

        Spearman correlation plot generated by deeptools. Spearman correlation is a non-parametric (distribution-free) method, and assesses the monotonicity of the relationship.

        Pearson correlation plot generated by deeptools. Pearson correlation is a parametric (lots of assumptions, e.g. normality and homoscedasticity) method, and assesses the linearity of the relationship.


        Peak distributions (macs2)

        DESeq2 - Sample distance cluster heatmap of counts

        DESeq2 - Spearman correlation cluster heatmap of counts

        DESeq2 - MA plot for contrast biological_replicates_st18.5_st7.5

        A MA plot shows the relation between the (normalized) mean counts for each gene/peak, and the log2 fold change between the conditions. Genes/peaks that are significantly differentially expressed are coloured blue. Similarily a volcano plot shows the relation between the log2 fold change between contrasts and their p-value.


        DESeq2 - PCA plot for biological_replicates_st18.5_st7.5

        This PCA plot shows the relation among samples along the two most principal components, coloured by condition. PCA transforms the data from the normalized high dimensions (e.g. 20.000 gene counts, or 100.000 peak expressions) to a low dimension (PC1 and PC2). It does so by maximizing the variance along these two components. Generally you expect there to be more variance between samples from different conditions, than within conditions. This means that you would "expect" similar samples closeby each other on PC1 and PC2.
